The accompanying drawing illustrates Illy partial plan and partial diagrammatic view. I

A is the receiving device and B and B1 the translating devices..` The receiving device `A is a polarized relay of a sensitiveness required for the line` of transmission, and suchline `may be eitheran overland or sub- I narine-4 cable.. The construction of such al polarized relay does not form part of this my Invention and/it is therefore only neces f sary to point out such'features ofthis relay through binding-post as arenecessary for the working of my system, and in this relay the polarized armatureis designated as a, the coils as d, and the pointsv of contact as b Zand c respectively. One terminal of the\ Coils d is connected 1 tothe line of trans' mission 2 the second terminal of thec'oils d is connected through binding-post 3 and Wire 4' to the ground c.V I have not shown here any of the devices customarily inserted in such lines or between such ground and lines, as my invention'does. not contemplate l a change in these special featuresjln Such".

Every' impulse sentover the line 2 will move the armature e of the device A towards respectively; S0 2*. VThrough the c'ontactingcf the armature a' with oneof these contacts c orb, the armature el oi the deviceB is moved towards and iny contact with one, ofthe contacts `c1 or b1 v u 85 3. Thecontactingofthe armature al with one or the otherof these' contacts c or t1 would connect the second lineoi transmission i 2*1 with one 'of thebatteries h or i were it not that as soon asv thecircuit including the electrc-magnet-B1 is made, the contact between its armature 7c andpoint m is. broken. r

To'eiiectually' connect the batteries i or h with the linejoftransmission 2a, it is therefore not onlyv necessaryu that the armature a1Y of the device B'shall connect with one of the contacts 'ctor b l, but'it is also necessary that atthe 'same time the electro-magnet B1 should remain denergized so asto allow the armaturek to remain in contact with the point'm., and this can only take Aplace during the time p that the armature a oi the device A is traveling from one contact to the other contact, andthe time Iperiod ior eac'h impulse owing over .the line 2a will -be e uall to the time period that elapses While t e armature a is traveling from one oivsaid contacts -to the lsecond of said contacts, and as this armature changes `its direction throu h every impulse. sent over the line 2 and as t e armature ai1 of 110 it is obvious that the impulse sentover the line 2a willnot onlybe ofthe same duration, but will always be of alternate polarity.

It is obvious that thearrangement may be alteredto suit re uirem'ents,'but in all cases polarized relayss ould .be employed and the connections be made lin such a mannerso as to allow'onlya predetermined timeperiod Y for `the transmission of' impulses through lineQ-a.,` It issuggested that in the practical work- 4 ing oi this device it should be agreed upon between both operators that, ait-er sending a message, one` im ulse shallalways be' trans'- mitted over the ine, this impulse to'be of a. direction so as to move the armature aoi the device A to the contactfc b, as agreedupon It is supposed thatfthe' contact agreed upon' is the point'c,

and it is supposedjhat to ysend //y,

the armature a in contact with c it requires the transmission of a negative impulse over the line. It should therefore be agreed between the two operators that in sending a `messagehthe first impulse to be transmitted should alwaysl be of positive polarity.

- Having now described my invention, what I claim as 'new and desire to secure by Letters Patent is l.. In combination with va line of transmission two polarized relays, one relay connected to sald line, the second relay connected to the contacts of the first relay, anA

electro-magnet, a second line oi transmission and means to connect throu h the move- 'ments ofthe armature of said e ectro-magnet said second line to a source of current.
